.AIR HEATING SYSTEM. A

Application tiled February 14, 1925.

My present invention relates to improvements in air heat-ing systems oi the ventilating type and utilizing a hot air furnace as thesource of heat for heating dwellings and other buildings adapted for the purpose. y

In carrying out my-invention I utilize a hot air furnace enclosed Within an air heating chamber which is adapted to receive cold aireither from the exterior atmosphere, or by circulation :from the interior oit' the house or divellinv.

Means are provided in the air heating chamber for humidifying the air as it is heated, and the gases of combustion passing from the furnace to the smoke pipe are utilized to radiate heat from the smoke pipe, which latter pipe extends in a vertical direction :trom the furnace through the building to an upper chimney section.

A heating drum is used in connection with the smoke pipe for heating the first floor rooms or compartments and a specially Yformed radiator for heat is utilized in connection with the smoke pipe for heating a room on the second floor ofthe dwelling. Hot air flues are. also utilized ttor distributing heated air throughout the rooms or coni- Vpartments of the secondlioor and additional means are utilized t'or distributing the heated air toV rooms on the first floor.

The distribution of heat and circulation of air throughout the entire` building or dwelling may With 'facility be eiiiciently controlled and the dwelling maintained at a required uniform temperature by a maximum use of the generated heat with a minimum 'fuel consumption. The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment oi my invention Wherein the parts are combined and arranged in accordance with the best mode I have thus tar devised for the practical application o't the principles of my invention.

Figure 5 is a transverse sectional View of a portion oi the hot air drum illustrating the manner ot' supporting the drum and a smoke pipe therein.

Figure 6 is a detail sectional View of the damper ot Figure il.

`While the invention is adapted -for various buildings I have illust ated herein a tivo story dwelling having a basement in which the hot air furnace designatedby the numeral l may be of any suitable or standard type and using an air drum 2. The furnace is enclosed Within a heating chamber 3 having Walls e' and this chamber is ot the desired size for heating cold air passed thereto. Preferably the chamber is rectangular with concrete Walls and oit course provided with al door for access to the iurnace. Under normal conditions the door is kept closed and the chamber is otherwise closed l,except for the air ducts as Will be described.HIJ

Cold air trom the exterior atmosphere may be conducted to the heating chamber through a cold air duct 5 built into the lioor o'lthe cellar, or cold air may be conducted to the heating chamber though a cold air duct 6 having communication with the first story of the dwelling.

As the cold air enters from either ot these ducts and rises from the bottom of the heating` chamber it is deflected toward the furnace by detlecting plates 7 attached to the Walls of the chan'iber, as in Figure l. These deflecting plates cause the air currents to pass in close proximity to the 'furnace trom which heat is radiated and heated air cur-4 rents pass up. through the chamber as indicated by the arrows.

For humidiifying or moistening the heated air I employ a series ot Water troughs S arranged in tiers, three in the walls ot the. heating chamber', from which, by evaporation the moisture is carried by the upwardly moving air currents. lVater to the troughs is supplied through the branch pipe 9 from the usual water pipes 9 of the dwelling.

rllhe smoke pipe l0 l0 rises vertically from the furnace and extends directly through the dwelling to a brick chimney ll passing through the root and supported in suitable manner. The top section l0 ot' the pipe telescopes in the chimney and said Section may be removed, when itis desired to dismantle the heating appliance, by tirst elevating the pipe section into the chimney to detach it from the ren'ainder ot the heating plant, and then withdrawingl it'tron'l the chimney.

rlhe smoke pipe rises through the first story ot the dwelling in .such manner as to radiate heat to several rooms, and these rooms, four in number as indicated in the drawings, are each provided with a licor register as l2, 13, le, l5, which close the top number, around 'of the heating chamber, il1 desired, or may be opened tor passage therethrough or air currents trom the heating chamber to the several rooms as indicated by the arrows in Figure l. These registers, or group of registers, are built into the tirst floor ot' the dwelling and heat is distributed :trom the four adjoining corners ot the respective rooms, the air circulatingas indicated by the arrows in Figure l. Atl a floor grate is provided which admits cool air from near the tloorto the cool air tlue li' which com.- municates with the horizontally extending cold air flue 6. The air currents are thus caused to circulate from the furnace., through the tour registers and the several rooms, and thence back to the heating chamber by way of the down draft tine l? and cold air tiue 6.

The intersecting partitions ot the tour first floor rooms are indicated in Figure 8 by the numerals 18, l), 2OV and 2l, and it will be seen that the fmoke pipe rises vertically through the junction of these'i'our partitions which arecut away or rather so built and constructei as to accommodate the smoke pipe and also a heating drum 22 which surrounds the smoke pipe and is designed to heat the tour adjoining rooms in addition to he heat suppl ed through the tour tioor regster l2, i3, lil and l5.

VlShe heating drum which is cylindrical in cros's section surrounds the smoke pipe and has a bottom opening 23 to the air heating chamber 8 and a top opening 2e on a level with the second floor of the dwelling-tor conveying hot air directly from the heating chamber to the .second floorV rooms or compartments, one ot the rooms being indicated as 25.

By means of the exterior brackets 26 the drum is attached to the tour partitions, and by means of bolts or retaining pins 2T the drum is centered in concentric position around the smoke pipe, asseen in Figure 5.

The movement ot' air currents up through the drum may be controlled by a damper best shown in Figure e, which is of conical formation when closed and located between the walls ot the smoke pipe and the drum, preferably just above the opening 23 to the air heating chamber. rlhis conical or frustoconical damper is made in sections, preferably two as 28 and 29, the two halves at their upper ends conforming to the periphery of the smoke pipe and the two halves at-their lower ends contorming to the inner periphery ot the drum. the sectionsv are hinged at tl'to the inner races ot' the drum'and the upper 'tree ends ofthe two halves are designed to swingen these hingesaway from or toward the smoke pipe. By means oifa litting knob 3l which projects laterally through a slot inE the drum (Fig. 6) a draw link 33 and alpairio'it` pivoted lin is and 35 the dampen is manipulated. The links and 35 are pivoted at 36 to the draw link-k 33 and also pivoted to the respective sections 29 and 23 ot the damper. By pulling up on the knob 3l in Figure 4 it will be apparentlthat the damper will be opened for free passage oit air currentsthrough the drum asindicated by the arrows in F igure'l.

The air heating drum 22-is -utilized to heat the tour iirst floor'A rooms 1 and l for this purpose a hot air duct 37 is attached to the eX- terior ot the drum in a corner of each of the tour rooms (Figure 3). These tour" duct-s have open bottoni ends terminating' just above the first floor andopen top :ends terminatingjust below the ceiling-'of the rst Hoor rooms to cause circulationv of air `in the several rooms as indicatedin Figure 1L For 'heating second vvfioor'- roomsother than the room 25 I provide lateral hot air ducts 38 and 39 projectedtroin the topv portion of the heating drum and located in the floor of the second story with floor outlets to the respective rooms Vas shown.

ln addition to the use of'the drum for conveying hot air to thesecon'dtloorroom 25, I employ a radiator indicated asa whole by the numeral t() which isinterposedbetween the pipe sections 4l0 and'lO. Asbest seen in Figure 2 thisV radiator is-'locatedat the desired level in thevroom `and comprises a central smoke flue 4l alinedfwith the two smoke pipe'sections l() and l0. The radiator has a lower horizontal perforated-plate l2 and an upper perforated plate 43 in the shape ot' disks, andbetween theseperforated plates is arranged an annuluaseriesot` short radiator pipes 44 spaced' somewhat trom the central flue 4l. Tapering flanges At their lower larger ends FEI? Inf)

' 45 and 46 at the respective lower and upper ends of the radiator connect it with the smoke pipe sections, and it will be apparent that the gases of combustion Will pass not only up through the central flue 41 but also through the pipes 44 and from all these elements heat is radiated to the room 25. By means of a damper 47 in the central flue the draft may be cut off therefrom and the gases of combustion directed entirely through the radiator pipes 44.

From the above description taken in connection with my drawings it will be appar ent that I have Vrovided a heating system whereby the entire dwelling may be uniformly heated or the circulation of air cut oif from one portion and concentrated in another portion or portions of the dwelling.

rIhe heating plant is compactly arranged and does not occupy undue space, and further it may be dismantled as for cleaning the pipes and lues or for storing parts away when not in use.

By rst removing the pipe section as described, the radiator in the second story may be removed from the pipe section 10, and then said section may be detached from the furnace and removed, for cleaning and storing, until further needed. rIhe hot air conveyers as well as cold air conveyers may readily be cleaned, and all openings, if desired, closed in some usual manner when the plant is not in use.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is 1. An appliance for distributing heat to adjacent rooms of a building comprising a heating chamber and a furnace therein and a plurality of registers in the top Wall of the chamber, a smoke pipe rising centrally through the chamber from the furnace, a drum encasing the smoke pipe above the registers, said drum opening into the chamber, and a damper in the drum above said opening. v
